This is a four point version of my Flexible Line project made by request of agruff91. See project http://scratch.mit.edu/projects/Paddle2See/728858 for the original 3 point version. Change the location (drag blue dots) or angle (drag green dots) at each of the four defining points and a new line will be interpolated between the points. Click on the background to hide/show all the controls. The Report button will tell you the X,Y,Direction of each of the four defining points. The Input button lets you type in the X,Y,Direction of the four defining points. You can separate the values with spaces or commas. Put all the values in on one line.
